STATES ATENT DISPENSER-HAVING STEP-BY-STEP ROTAT- ING VALVE'.IYVITIZLMEANS'i'lQ` PREVENT VERSERQTATION THEREOF My invention relates-to improvements in nicas,- uring and dispensing devices,- for use especially, although not necessarily, as a household appliancefor measuring and dispensing from jars, and the like.

The primary object of the invention is tol pro,- vide a simply constructed, inexpensivedevioefcr attachment to a wall, or shelf, and toWhCh a screw-,threaded jar of granulated coffee, or other comminuted material, may be attached in inverted position to discharge therein, the device being adapted for easy repeat operation todispense such material in uniformly measuredquantities without clogging of the material either in the device or inthe jar and without admittingair into the jar, whereby thematerial in the jar will not deteriorate from exposureto atmospheric air.

To the accomplishment of the above, and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompany-ing drawings, Aset forth in detail in the succeeding description, andrillledfn the claim appended hereto.

In said drawings:

Referring to the drawings by numerals, according to my invention, as illustrated, a cylindrical, cup-like receptacle I is provided, of any suitable light, strong material, such as aluminum, and which embodies an enlarged rim cuff section 2 threaded for screwing onto the threaded neck 3 of a material supplying jar 4, especially one for containing ground coffee. Preferably the cuff section 2 is threaded for application to the wellknown Mason jar of commerce. The receptacle I is provided on one side thereof, constituting its rear side, with a hook-like lateral arm 5 for insertion downwardly into a suitable wall tached to such a base,ias a wall, or shelf, to A. either a permanent or remvabl .ftlltebottomv 'I of the receptacle I has formed therein .tion2 and-rests on thebottom l of saidre'qep ole.

A rotor operating member 23, in the form of a split, resilient, at metal ring, with overlapping ends, is rotatably mounted in an internal, circumferential groove 24 formed in the receptacle I immediately below the ledge I4. The rotor operating member 23 is retained in the circumferential groove 2t by the cover plate I3 and the rotor section 9, which it surrounds. A hand-grip stud 25 extends laterally from the outermost end of the rotor operating member 23, out of a circumferential, arcuate slot 26 formed in the front of the receptacle I, and whereby said member 1s rotatable back and forth, forwardly and rearwardly, respectively. The ends of the slot 26 limit forward and rearward movement of the rotor operating member 23 by engagement with the handgrip stud 25, and the extent of movement of said member 23 is limited to an arc of substantially 90. The innermost end of the rotor operating member 23 forms a resilient, ratchet tongue 2l adapted to engage one side of the impeller blades I, successively, and rotate the rotor section 9 counter-clockwise, as viewed in Figure 4, step by step upon repeated movement of said member forwardly, said tongue 21 being adapted to ratchet over the side edges of said blades I6 when said member 23 is moved rearwardly, and snapping behind said impeller blades IU, successively.

A washer-like, reverse rotation plate 28 is cireurnposed on the stud 2l and rests on the upper end of the rotor section 9 between said end and the cover plate I3. The reverse rotation plate 28 is provided with a pair of circumferential, resilient, hooked tongues 29, 29 engaging the edges I6, Il of the cover plate I3, whereby said plate is prevented from turning about the stud 2 I. A third circumferential, resilient tongue 3U on said plate 23 is adapted to wipingly engage the upper edges of the impeller blades I6 and to snap downwardly behind said blades and thereby block reverse rotation of the rotor section 9 when the rotor operating member 23 is moved rearwardly.

An auxiliary rotor section 3l, shorter than the rotor section 9, but otherwise a duplicate thereof, with the excepion presently noted, surmounts the cover plate I3 and adapted to extend into the neck 3 of the jar 4 to act as an agitator. The auxiliary rotor section 3| is detachably attached to the rotor section 9 with its blades 32 vertically aligned with the impeller blades I0. For this purpose, said section 3l is provided with an axial socket 33 threaded onto a stem 34 arising axially from the stud 2|. As will be understood, the blades 32 o f the auxiliary rotor section 3i clear the cover plate I3 suiiciently for working purposes.

As will now be apparent, the impeller blades I9 of the rotor section S are adapted to form in conjunction with the closed bottom, measuringr pockets in the receptacle I, which, when the rotor operating member 23 is rotated repeatedly from its rearward limit of movement, counter-clockwise, into its forward limit, as shown in Figure 4, ,1

will be registered successively with the discharge opening 8 so that said pockets will discharge out of said opening 8 successively. As will also be clear, in either limit of movement of the rotor operating member 23, one of said pockets registers with the discharge opening 8, and the others are positioned for feeding of material into the same through the feed opening I8, one of said other pockets being fully registered with said opening I8 and the others being partially registered therewith. Thus, in either limit of movement of the rotor operating member 23, and during rotation of the rotor section 9 between its limits of movement, said pockets will be fed so that a completely filled pocket is always provided for rotation to the discharge opening 8. The edge I. of the cover plate i3 levels off the pockets as the same approach the discharge opening 8. The auxiliary rotor section 3| agitates the material in the neck 3 of the jar 4 to provide for free discharge out of said neck and to prevent clogging above the rotor section 9.

The foregoing will, it is believed, sulce to impart a clear understanding of my invention, without further explanation.

Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

What I claim is:

In a measuring and dispensing device of the type including a receptacle having a cover plate with a feed opening therein, a bladed rotor adapted to iit in the receptacle and be rotated in one direction therein, said rotor having a stem joui-nailed in said cover plate, and an apertured reverse rotation plate fitted around said stem between said cover plate and rotor with tongues thereon engaging the edge of said cover plate at said opening to anchor the reverse rotation plate to said cover plate, said reverse rotation plate having a depending resilient ratchet tongue for wipingly engaging the blades of the rotor and flexing downwardly between the same to block reverse rotation of the rotor.
